SPECIFICATION forming part of Letters Patent No. 655,6451, dated August '7, 1960. Application filed January 5,191002- Serial No. 411. (No model.)

T all whom it may concern:

Be it known that we,W ILLAM'II. BAKER,l residing at CentralfFalls, Pro''vid encevcoui,1ty, Rhode Island, and FREDERIC EgKIP, residing.l

at Montclair, Essexcounty, New Jersey, citi-k zens of the United States, have invented cer- 4 tain new and useful Improvements in Looms, of which the following is a specification.

This invention relates to weft or lling 1o changing or supplying mechanism for looms, and particularly to such as feed or supply bobbins in weft or bobbin holders or cases to the shuttle of a loom automatically as required.

The present invention includes an improved shuttle to receive the weft or bobbin case, an improved weft or bobbin case, improved electrical devices whereby a circuit is closed when the weft on the bobbin is nearly zo or quite exhausted,an improved rotary magazine for carrying the weft or bobbin cases and bobbins, and improved means for controlling and operating said magazine.

In the accompanying drawings, which illustrate an embodiment of the invention, Figure 1 is a side elevation, on a relatively-small scale, of a loom embodying the invention. Fig. 2 is a side view of the magazine and adjacent parts, partly in section. Fig. 2 is a 3o fragmentary view of the end of the magazine opposite to that seen in Fig. 2, and Fig. 3 is a sectional front elevation of the magazine and adjacent parts. Fig. 4. is a side elevation of the shuttle, containing a bobbin-case and bobbin. This view is on a larger scale than Figs. 2 and 3. Fig. 5 is a much-enlarged fragmentary sectional view of the shuttle, bobbin, and bobbin-case. Fig. 6 is an enlarged plan view of the bobbin-case, partly 4o in section 5 and Fig. 7 is an end view of the same. Fig. S is a view showing the spindle detached. Fig. `9 is a sectional view of the bobbin or weft holder detached. Fig. 10 illustrates a slightly-modified form of the magneto-mechanical device. Figll is aviewillustrating howthe contact-terminal in the bobbin is held against the centrifugal force tending to throw it ont during the winding. Figs. 12 and 13 are views illustrating a construcis dispensed with. Figs. 14 and 15 are views forming. a part thereof.

tion wherein the spindle in the bobbin-casel showing1 how mechanical controlling "means employing a feeler may be used in place of electrical controlling means.

1 isnthe loom-frame. 5 2 is the breast-beam,` 55

` 3 is the lay. 4t is one ofthe lay-Swords. 5 is the reed carried by the lay. 6 is the crank-shaft, which imparts vibrating movements to the lay, and 7 is one of the connecting-rods which couple 6o the cranks of the "crank-shaft to the layswords. All of the above parts are common in looms.

Mounted on a suitable bracket 8 on the loom-frame is a rotary holder or magazine M for the bobbin-cases 9, and this magazine is rotated by a belt 10, which is driven from a sheave or pulley 1l on a shaft of the loom, the crank-shaft 6 being the one employed herein. The belt 10 is not so tight but it may slip on 7o the sheave or pulley 12 on the magazine when the latter is held against rotation, as it is, habitually, by a fixed detent 13, which occupies a position in front of that bobbin-case 9 in the magazine which is directly over the shuttle-box 15 on the lay when the latter is in its advanced position, as seen in Figs. 1 and 2.

The magazine M has a boss 16, Fig. 3, rotative about a fixed spindle 17in the bracket 8o 8, a head 18 on said boss, and arms 19 projecting from said head parallel with the axis of the magazine. The bobbin-cases 9 are supported at one end by spring-lingers 20, se-

cured to the outer face of the head 18, and at the other end by spring-plates 21, Secured to the respective ends of the arms 19. These latter occupy positions between the respective bobbin-cases in the magazine and alternate with them. i 9o The magazine may be of such size as to take in any reasonable number of bobbin-cases, but as herein shown it contains twelve. It may be said here that the bobbin-case is cylindrical, and in order that it may be properly 9 5 placed in the magazine without difficulty it has at one end a recess or gain 22, which fits a squared part of the recess in the head 18 when the bobbin-case is properly placed.

The detent 13 arrests the rotation of the loo magazine when the shuttle 24 is in the shuttle-box 15, directly under the lowerrnost bob- ,a estim bin-case `v`in the magazine. The shuttle is open at the bottom, and the lay at the bottom of the shuttle-box has also an opening 14 under the shuttle, (see Fig. 2,) so that in supplying a fresh bobbin-case from the magazine the fresh case may be driven downward, so as to knock from the shuttle the case containing the exhausted bobbin and take its place. The means employed for driving the bobbincase down into the shuttle consists of adriver 25, comprising a lever fulcrumecl on the loom-frame at 26 and having a head 27 on its longer arm, which extends into the magazine at its open innerend and stands directly over the lowermost bobbin-case in the'magazine. To the other and shorter arm 23 of the lever 25 is hinged the armature-lever 28 of an electromagnet 29, mounted on the loom-frame. When this magnet is excited, it draws down the armature-lever into the path of a tappet 30 on the lay, and when the lay beats up said tappet impinges on the armature-lever and through it rocks the lever 25, causing its head 27 to descend upon and drive down the bobbin-case below it from the magazine into the shuttle in the box below, thus displacing the bobbin-case therein. A suitable spring, as 31, normally upholds the driver.

The specific construction of the shuttle, the bobbin-case, the bobbin, and the electrical appliances will now be described.

As before stated, the shuttle has an opening at the bottom as well as at the top, the cavity of the shuttle extending down through it, and in the shuttle, at each end of said cavity, is a pair of laterally-spaced springjaws 32 to hold the bobbin-case 9 in place. In the lateral faces of the bobbin-case, at its respective ends, are vertical grooves 33, which are engaged by said jaws. Thus the bobbincase is held in place with sufficient iirmness, but may be displaced downward by the incoming case from the magazine. As before stated, the bobbin-case is cylindrical, and it has (in the principal views) a spindle 34, hinged in the case at its metallichead. This spindle is seen detached in Fig. 8. On it is a sliding metal washer or disk 35, backed by a spring 36, which is between said disk and the head of the spindle. The metallic bobbin-case is in two parts, connected together, but insulated from each other electrically by insulating material 37. (Seen clearlyin Figs. 5 and 6.) Consequent upon this construction one end of the bobbin-case-that at the left in Figs. 5 and 6-is electrically connected when the bobbin-case is in the shuttle,through the spring jaws 32 and a conductor 38, with a metal contact-plate 39 on the side of the shuttle at that end, and the other end of the bobbin-case is connected electrically through the spring jaws 32 at that end of the shuttle and a conductor 40 with a metal contact-plate 39 on the shuttle at that end of the latter. The insulation of the two sections of the bobbinv case may be eected by causing one section the insulating material 37, as seen in Figs. 5 and 6. y

The construction of the bobbin or weft holder 42 is best seen in Figs. 5 and 9. It may be of any suitable form. As here shown, it is tubular and slips over the spindle 34, and it has at its butt an exteriorly-placed flanged metal ring 43 and an interiorly-placed metal ring 44. When pushed onto the spindle, the ring 44 bears on the disk 35 and is in electrical connection therewith, and the ange on the outer ring 43 wipes over and engages the free end of the metal spring 41, mounted in the bobbin-oase and electrically connected with the section thereof at the right in Figs. 5 and 6. This spring 41 is in the nature ofa conductor as well as a retainer for the bobbin.

Mounted in a longitudinal slot in the butt portion of the bobbin is a spring-actuated contact-lever 45, fulcrumed at 46, the longer arm of which is held up into contact with the inner face of the outer ring 43 by a spring- 47, connected electrically with the inner ring 44. The free end of the spring 47 contacts electrically with the lever 45 between the ful- Crum-point 46 and the ring 43. The shorter arm 48 of the lever 45 projects, under these conditions, (see Fig. 9,) into the bore or hollow of the bobbin which is to receive the spindle 34, and when the bobbin is on the spindle (see Fig. 5) said arm 48 comes opposite to a recess 34X of sonne kind in the spindle, as clearly shown in Figs. 6 and 8. The purpose of this shorter arm on the contact-lever will be hereinafter explained.

The magnet 29 and a generator 49, Fig.v3, are in a normally-open electric circuit represented by conductors 50, which have springcontact terminals 51 and 51 at the side of the shuttle-box 15, these box-terminals being so placed as to be put into electric Contact, respectively, with the plates 39 and 39 on the shuttle when the latter enters the box. Now if the long arm of the contact-lever 45 be pressed into contact with the outer ring 43 on the bobbin and the shuttle is in the shuttlebox the current will flow from one pole of the generator 49 to and through the coils of the magnet 29, thence to the spring, box-contact 51, thence to the contact-plate 39 on the shuttle, thence byconductor 38 and one pair of jaws 32 to the section of the bobbin-case seen at the left in Figs. 5 and 6, thence through the head of the spindle, the spring 36, and the washer 35 to the inner ring 44 on the bobbin, thence through the spring 47 to the contact-lever 45, thence to the outer flanged ring 43 on the bobbin, and through it and the retaining springplate 41 to the section of the bobbin-case at the right, thence through the jaws 32 at that end and the conductor 40 to the contact-plate 39X on the shuttle, thence to the spring-box terminal 51X, and thence back to the other pole of the generator.

The contact-lever 45 is so bent or curved outward that when it makes contact with the ring 43 it projects out through thel slot in the IOC) IIO

bobbin;a but when the weft or filling w is wound on the bobbin, as seen in Fig. 5, the

lever is held pressed inward, so as to keep it out of contact with the ring 43 and also to.

\ pleted through the magnet 29, the armaturelever will be moved into the path of the tappet 30 on the lay, and the movement of the lay will cause the driver-head 27 to drive a fresh bobbin-case from the magazine down into the shuttle-box, displacing the'exhaustcd one therein. When the lower bobbin-case is displaced from the magazine and the head of the driver is retracted, the constantly-running belt 10 will rotate the magazine M until the next bobbin-case therein comes t-o a bearing on the detent 13. The belt will slip by preference on the sheave 12.

The shuttle is cut down at the side, so as to permit the filling or weft-thread from the bobbin to take its proper place, said thread being primarily threaded through a guidingeye 9 in the bobbin case. The several threads from the bobbins in the magazine M may be led out and attached to a suitable holder 52 thereon, as seen in Fig. 3.

Fig. 10 shows how the armature-lever may be made to support a lever 28X, pivotally coupled to the arm 23 of the driver, this lever 2S taking the impact of the blow from the tappet 30 and relieving the armature-lever of same. v

Figs. 12 and 13 show a construction where the bobbin or weft holder is mounted in the bobbin-case without a spindle. The points of difference between this construction and that before described will be explained. The bobbin 42 in this construction is the same as that seen in Fig. 9, except that the outer` ring 43 is grooved and embraced by springjaws 53, mounted on and electrically connected with the section of the bobbin-case at the left, while the inner ring 44'/ is in contact electrically with an upturned end on the spring-plate 4l, which has the eect to put the spring 47 in electric contact with the right-hand end or section of the bobbin-case. Otherwise the construction is the same as before described.

In winding the weft or filling on a bobbin or weft holder having a contact-spring held out of contact (so as to' break the circuit) by the overwrapped yarn it is found that the centrifugal force developed by the rapid rotation ofthe bobbin on the spindle of the windingframe tends to throw out the contact-spring with a force greater than that exerted by the tension of the yarn, and consequently the yarn does not always maintain a break between the contacts. Therefore in order to overcome this difficulty the contact-lever 45 of this invention is provided with the short arm or heel 48, extending into the bore of the bobbin, and when the latter is slipped onto the spindle 54 of the winding-frame, Fig. 11, the said spindle displaces said arm 48 outward, and by rocking the contact-lever on its fulcrum draws in the longer arm thereof and holds it drawn in against the centrifugal force tending to throw it outward, thus permitting the yarn to be wound on the bobbin properly. If the bobbin be afterward slipped onto a spindle, as 34, and this latter be provided with a recess 34X, as described, the said re-` cess will provide room for the arm 48,` so that the lever 45 may make contact with the outer ring on the bobbin:

By bobbin as the word is herein used is meant any suitable form of holder for weft or iillin'g. 'These holders have several names in the art. By weft or bobbin case. as the phrase is herein used is meant any suitable holder for the bobbin.

It will be noted that we employ in carrying out our invention albobbin case or holder which is driven down into the shuttle or weft carrier, and it may be explained that this avoids the necessity of employing what is denominated a self-threading shuttle.-

These latter do not thread themselves with certainty and are not well adapted to all kinds of weft or filling. In our construction it is only required to cut down the side of the ordinary shuttle to allow the thread or yarn from the eye 9 on the bobbin-case to pass out. This eye 9X will by preference be tubular, as seen in Fig. 6, and will have a pad or brush to put the proper tension on the yarn.

Our invention may be employed in connec- -tin with mechanical controlling mechanism in lieu of electricalfor example, that illustrated in our pending application, Serial No. 410, filed January 5, 1900. Such mechanical controlling mechanism is illustrated in Figs. 14 and 15, the former being a vertical longitudinal section of a part of the shuttle and the inclosed bobbin-case and the latter a plan of the same. In these views the free outer extremity of the lever 45 is provided with a detent-head 45X, which is held down or in out of the path of a feeler 55 by the overwrapped filling or yarn on the bobbin; but when the filling is substantially exhausted the spring 47 presses said lever outward until its detenthead comes int-o the path of the feeler 55, when the latter will be pressed back, and thus cause the lay in beating up to actuate the driver 25. Afeeler of this general character is illustrated in our beforementionedpending application, Serial No. 410, and a feeler to set in operation the weft-supply mechan= ism by impingement on an indicator when the weft in the shuttle in play is substantially exhausted is shown also in our pending application, Serial No. 4,221, led February 6, 1900.

which will be coincident with the arm or heel 48 when the bobbin is in place to allow the indicator 45 to operate when the weft or iilling is substantially exhausted, and it is ob.

vious that a spindle of this character would permit the indicator to operate ifmounted in a shuttle as it would if in a bobbin-case.

I In order to cushion the blowof one bobbin- 'clase on another when the incomingy case drives out that in the shuttle, the bobbincases may be provided at each end with cushions 56, of rubber or similar material, as shown in Figs. 5, 6, 7, 13, and 14. These cushions may be constructed and applied in any manner suited to eftect the obj ect sought and may be on the top` or bottom of the case or on both the top and bottom.

By weft-holder as herein expressed is meant any receptacle holding weft or illing, such as a weft or bobbin case containing weft orlling, or bobbin, butt-cop, cop, and

the like containing weft or filling.

Although we have illustrated herein a wef tcase or bobbin-case, we do not Wish to give undue prominence thereto, as our speciallyconstructed magazine is also adapted to take any known form of weft-holder.
